4 Claims.

This invention relates to railway track crossings and has for its objects a more durable, rigid, easily assembled, quiet operating structure, with easily renewable track sections and wearing parts. Other advantages of the invention will appear in the following description and accompanying drawing.

In the drawing Fig. 1 is a plan view of my improved crossing with one of the inner rail sections displaced to show its lateral removal or assemblage.

Fig. 2 is an enlarged plan view of the silencing cross which fits into the flange grooves of the crossing rails.

Fig. 3 is an enlarged elevation partly in section, of a portion of Fig. 1 as seen from the line 3-3 thereof.

Fig. 4 is an enlarged section of a portion of Fig. 1 as seen from the line 44 thereof.

Briefly described, my improved railway crossing comprises a unitary steel casting 1 supporting four crossed rails 2 as shown in Fig. 1 and with the ends of the casting terminating a distance 3 equal to half the distance to the rail of the next crossing when used with double track crossings as indicated in dotted lines at 1' in Fig. 1.

This casting is a deep section rail high at the points i of actual crossing of the rails only and at all other points it is lower than the rails 2 and of complementary form as shown in Fig. 4 to fit nicely against one side of the rail as at 5, overlie the lower flange of the rail as indicated, and also present a solid continuous foundation 6 for the bottom of the rail as shown.

The casting itself is provided with lower flanges 7 pierced by holes 8 for spiking down as at 9 to suitable ties 10 if desired, or it may be mounted on a concrete foundation if desired. The ends of the rail sections 2 are squared off as are the shoulders of the more elevated portions of the casting so that all of the rail sections may be put in place directly from the side as indicated in Fig. 1 and then bolted through the standing web to the vertical web 5 of the casting as by bolts 11. The outer rails from the main run may also be put in place from the side orthey may be shoved in from the end if desired, and when double track crossings are installed the intermediate rail section Z'straddles the butt joint 12 of the castings and is of a length to abut the shoulders of the rail-high portions of the crossing, so that when interlocked under the standing webs 5 of both castings and firmly bolted against them an absolutely rigid assemblage is produced.

ing as by horizontally extending bolts 15. These I crosses are low enough at their ends for the flange 16 of a car wheel 17 to ride over and are slanted upward to gradually take the weight of the car at a the point of crossing so as to do away with all hammering through the wheel tread striking the edges of the crossing groove. The crosses are of high wearing quality of steel or alloy and lit tightly in place to prevent rattling, hence as their removal when worn might be difficult I provide slotted holes 18 through the casting to permit insertion of a bar or wedge for prying them out from below, as will be readily understood from a consideration of Fig. 4. Where one line of traffic is much greater than the other so as to produce uneven wear on the silencing crosses, they may be removed, given a quarter turn, and replaced.

It will be evident from the above description that where the crossing rails of one line are of different size section than the other, that the casting will be made to suit as it must be complemental to the form of the rail with which it interlocks and supports.

I claim:

1. A railway crossing structure formed of a single casting comprising a rectangular base frame having a plurality of track-high rail crossing blocks cross-grooved for the wheel flanges, and standing webs on the base frame extending in line with the rails from said track-high crossing blocks adapted for lateral bolting of continuing rail sections thereto, the crossing grooves in said blocks being considerably deeper than required for the wheel flanges, and a separate flange-riding cross fitted tightly in the groove in each block, bolts extending transversely through both the block and the arms of the cross and the side of the block slotted for inserting a pinch bar under the cross.

2. A double track crossing structure comprising a pair of castings of similar shape and size positioned side by side, each casting comprising a frame in the form of a four-sided parallelogram having four track-high rail crossing blocks at the four corners thereof cross-grooved for wheel flanges, base members formed on said frame extending outwardly beyond each crossing point arranged and adapted to support rail sections thereon in line with the cross-grooves of the crossing blocks respectively, the base members on adjacent sides of the rectangular frames respectively substantially abutting at their outer ends at point ssubstantially equal to one-half the 5 distance between the frames.

. cross-grooved for wheel flanges, said base frame adapted for supporting continuing rail sections thereon between the crossing blocks of each frame, and the base frame extending outwardly beyond each crossing point, the extensions on adjacent'sides of the rectangular base frames respectively substantially abutting at their outer ends at points substantially equal to one-half the distance between the frames, said abutting ex-V tensions being arranged and adapted to support connecting rail sections thereon.

4. A double track crossing structure comprising a pair of castings positioned side by side, each casting comprising a rectangular base frame having four track-high rail crossing blocks crossgrooved for wheel flanges and standing webs on the base frame extending in line with the rails from said track-high crossing blocks adapted for lateral bolting of continuing rail sections thereto, the base frame and standing webs of each casting extending outwardly beyond each crossing point, the extensions of the base frame and standing webs on adjacent sides of the base frames respectively substantially abutting at their outer ends at points substantially equal to onehalf the distance between said castings.
